As an update for me:
Zen Purchase made 6/22 @ 6:20pmPST
Zen Review completed 6/23 @ 11:00amPST
Zen transfered to C-Points and confirmed C-Point in game- no problems, save for the inconvenient delay.
Purchased Zen again and I confirm the transaction is immediate- no problems.
So, it appears... Mind that first step, it's a looloo! LOL
